My mistake. I misunderstood the meaning of -msse3 (it only enables the sse3 builtins). Please ignore.

Hi,

I know this has been discussed in bug 18668. But I'd like to bring it up again.

Currently, fisttp is only generated with -march=prescott. The argument is fisttp is not a SSE instruction. While this is technically true, it's likely to surprise the users. Intel, after all, does lump fisttp in SSE3. AMD64 architecture programmer's manual also explicitly state fisttp is a SSE3 instruction.

Please consider enabling fisttp with -msse3.

Thanks,

Evan
